RESILIEN'I SHOCK-ABSORBING I-IUB UNIT.

Speccation of Letters Patent. Patnted Sept. 25, 1917.

Application led March 19, 1917. Serial No.` 155,792.

To all whom t may concer/n:

Be it known that I, GEORGE T. GREELEY, a citizen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Resilient Shock-Absorbing Hub Units, of which the following is a specification.

My invention relates to vimprovements in resilient shock-absorbing hubs, and the object of my improvement is to supply an interchangeable hub which comprises coacting resiliently mounted elements and interchangeable anti-friction means adapted for use on a vehicle wheel or other wheel where it is desirable to prevent the communication of peripherally received shocks to the axial body on which the wheelA and hub is mounted.

This object I 'have accomplished by the means which are hereinafter described and claimed, andV which are illustrated in the accompanying drawings, in which Figure 1 is a central axial section of my improved shock-absorbing hub; Fig. 2 is a like section through the concentric spring-containing rings only of said hub; Fig. 3 is a transverse section of said spring-containing rings showing the radially disposed springs mounted between them; Fig. 4 is an elevation of the outer end of said hub with parts broken away; Fig. 5 is a detail view of a link-connection of said hub, and Fig. 6 is a like section to that of said Fig. 2, but showing a modied type of spring mountings positioned therein.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring to Fig. 1, the numeral 2 denotes one end of a relatively fixed tubular housing. 1 is one end of an axle rotatably mounted in said housing. Upon said housing is tted a sleeve 8 which extends only part way toward the end thereof, and on that part of the housing not so covered are mounted the like spaced sleeves 7 having inclined bearing surfaces or runways for the anti-friction rollers 6, but reversed in relative positions. The end of said housing 2 has exterior threads on which are mounted nuts 9 and 11 and an intermediate washer 10 abutting upon the outer end of the outer sleeve 7.

Runway inclosing rings 5 are. mounted between the rollers 6 and the concentric hub 4. The hub 4; has an integral friction rim 8 to form part of a friction-brake device. .Upon said hub, a ring 16 is secured by means of a key 27 A disk 83 is positioned concentrically about the hub l in contact with the outer face of 4the web of the frictionsrim 8, spaced from said hub, and has an outwardly extending rim part 25 spaced concentrically from the hub and containing a ring 17 secured 'thereto by means of a key 26.

The'rings 16 and 17 have opposed bosses 34, which latter have hemispherical socketbearings 35 to movably receive the hemispherical outer ends 36 of telescoping spacing-elements 1S and 19. Coiled compression springs 20 are mounted about said telescoping members 18 and 19, engaging integral annuli 37 thereon. f

The numeral 15 denotes a face-plate mounted overthe rim part 25, and has a depressed annular flange between which and the said disk are positioned the. inner ends of spokes 22, these parts having alined orifices to receive bolts 21'fastened by nuts 23.

The axle 1 has an integral disciform ex tremity 12. A raised annular center disk 14 bears against the outer `end of the hub 1, being positioned between the hub and the disk 12, said parts being secured together by means of machine-screws 13. has an oriliced radial arm 29. A pivot-pin 31v is mounted ixedly in the flange of the face-plate 15, another pivot-pin 30 is secured in the orifice of said arm 29, and a link 32 is used to pivotally connect the pins 30 and 31, `thus establishing a driving-connection between the driving axle 1-12 and the wheel-spokes 22. A

It willl be observed that the parts of my device are readily demountable, and as quickly re-assembled, for removal of the face-plate 15 permits insertion of the springcarrying rings 16 and 17, while it is only necessary to remove the disk-plate 14, after the axle 1 has been displaced upon the removal of the screws 13, to allow placing or removal of the anti-friction elements 6 and 7 of the hubbearing. On this account, repairs are readilyV effected, substitutions of parts made, and it is made possible to employ standardized anti-friction bearings as well as standardized resilient connections itloilo the relatively movable elements of the I have shown in Fig. 6 a modified form of spring-mounting of a simpler type', the antifriction supporting bodies 28 for the ends of The disk 14.--

-the springs 20 answering forthe telescopic members 18 and 19 shown in said Fig. 2, and

being cheaper as well as interchangeable,

but it is evident that other forms of resilient connections and supporting' means therefor larged end of said axle, said hub having anV integral annular flange, an annular web positioned coaxi'ally about and spacedk from said hub'in contact with said annular flange,

" said web having an annular ii'mcoaxial with the hub and spaced therefromhspaced annu,- lar cylindrical rings positioned between said hub' and said annular rim and keyed thereto respectively to permit relative longitudinal displacement only of the rings, an annular face-plate detachably secured` to said web and centrally offset to cover the interspace of said hub and annular rim, radially disposed resilient elements engaged between said hub and annular rim, and separable relatively movable connecting means between said axle, said hub and said web.

In combination, a relatively fixedftubular housing, an axle rotatably mounted Y within the housing, and having its outerY end projecting therefrom, v a hub rotatably mounted upon the housing, an annular rim positioned coaxially about and spaced from said hub, separable relatively movable connecting means between said rim, said hub and the said projecting partof saidaxle, yieldable resilient means positioned between said rim and saidhub, means `connected to said hub for closing the opposite ends of the interspace of said rim and hub, and means connected to said housingk for preventing longitudinal displacement vof said .rim rela-v tive to saidhub. f
